Mark,

The V7 will pass data from the GPS source through to XC Soar.

You said you would connect a Nano to the V7, but to get the flarm info. you either need an IOIO board that will take the signals from both the V7 and flarm into the tablet, or mpre simply use the flarm as the GPS source for the V7.

This will allow the flarm info to be passed through the V7 to XC Soar via the V7 bluetooth module.
